TO ALL WHOM IT MAY CONCERN:

Be it known that we, Erzoon S. YENTZER and ALFRED K. McCain, of Ottawa,in the county of La Salle, and State of Illinois, have invented a newand improved Feller for Sewing-Machinery; and we do hereby declare thatthe following is a full, clear, andexact description thereof, referencebeing had to the accompanying drawings, making a part of thisspecification, in which- Figure 1 is a perspective view of the fellerapplied to the foot of a sewing-machine, and provided with an adjustableguide.

Figure 2 is a perspective view of a feller without an adjustable guide.

Figure 3 is a perspective view of the bottom of the feller of fig. 2..-

Figures 4 and are enlarged views of the feller of -fig. 1.

Figure 6 is an end view of the turning portion, and the guide of fig. 1.

Similar letters of referenceindicate corresponding. parts in the severalfigures.

This invention relates to a new and improved device, which may bereadily attached to the resser-foot of a sewing-machine, or removedtherefrom at pleasure, and which is designed'for turning under the edgeof cloth inmaking what are known is felled or lapped scams. In makingthese seams, the material is first stitched, so as to leave one'verynarrow edge, and one which is much wider. This latter edge'requires tobe turned under once, and stitched or felled down.

his the object of our invention to perform this operation of felling orturning down the wide edge, upon a sewing-machine, without previouslybasting it down, by means of a simple device, consisting chiefly of athin plate having one of its edges bent,'so as to form a taperingturning portion, and a gauge or guide, which latter lies close to theseam first made, and leaves the work straight, as will be hereinafterdescribed.

To enable others skilled in the art to understand our invention, we willdescribe its construction and operation.

In, the accompanying drawings, figs. 2 and 3, 11 represents thedevice-for turning under the edge of a piece of cloth, which device ismade of a thin plate, bent about as we have represented; that is to say,one portion of the plate is turned under more than the other, so as toform an enlarged entering-portion, terminating in a fiat throat, thuscausing the edge of the cloth to be gradually turned under as it movesbeneath the presser-foot A. This turner a is secured firmly to the sideof gauge or guide 6, the lower edge of which projects slightly below theupper edge of the turner, nearest the throat thereof, as shown in fig.3. The guide 6 terminates in'a curved arm or holder, 0, the end of whichis bent at right angles to its guiding portion for the purpose ofentering a hole made through the bar of the resser-foot A. 7 By means ofthethumb-screw d, the arm a and its guide and turner are secured fast inplace.

For stitching the first scam, the device may be removcdfrom thepresscr-foot by loosening the thumb-screw d, or, if desirable, thedevice may-be turned up out of the way and held in this position. Theturner a should be so adjusted, with relation to the pressing surface ofthe foot A, that the turned seam will pass beneath this portion, and besmoothed as it advances to the needle.

In figsl, 4, 5, and 6, a feller is represented, in which the plate, onwhich the turning portion a is formed, is slotted, for the purpose ofallowing the square neck, a, of a scrcw'to pass through it. This screwis formed on a right-angular piece, f, the vertical portionof whichforms the gauge or guide, shown clearly in fig. 6. The screw receivesupon it a thumb-nut, g, by means of which the guidef can be adjusted andset at any required distance from the turner a, for stitching wide ornarrow i'ells. The plate a, on which the turner at is formed, is securedrigidly to a wide plate, B, that is curved upward, as shown in figs. 1and 4, and provided, on its upper end, with a pin, it, that passesthrough the bar of the p'resser-foot A, and is held fast by the thumbscrew The curvedplate B lies close to the side of the resser-foot, andthe turner-plate ais secured to this plate, so that the turner aprojects from its side, and'is brought in or nearly in line with thepressing surface of this foot, so as to present a flatly-prossed'seam tothe needle.

The plate B is made of some suitable spring metal, so as to keep thecloth down close upon the bed of the sewing-machine while the feedrises, preparatory to and during the act of moving the work beneath theneedle If desirable, a portion of the turner a may be split, asindicated in red, fig. 1, so that it. will have xi slight elasticity. I

Having described our invention, what we claim as new, and desire tosecure by Letters Patent, is- 1. The attachment of both the singleturner a and the gauge or guide I; to the presser-fdot, by the meansand'ip the manner substantially'hs herein described. 1

2. The single turner a, in combination with an adjustable gauge orguide,f, adapted for falling sea-ms, substantially as described. v

The attachnient of the turner a of a. feller to an elastic holding-plateB, substantially as described..
